The Opportunity

Problem

Students building web3 study group platforms can't convince peers to use crypto wallets for simple tasks like sharing notes, resulting in zero adoption.

Solution

GhostGroup provides embeddable widgets and APIs for student devs to add walletless onboarding to their platforms. Users sign up with email or social login; backend creates and manages proxy wallets for web3 actions like note ownership. Peers share notes seamlessly without ever seeing wallet prompts, driving instant adoption.

Target Audience

Student developers building web3 study group platforms targeting college peers

Differentiator

True wallet invisibility using secure backend proxies, unlike clunky social logins that still require eventual wallet connection.
